As a rule, first a person tries to solve the problem on their own. He searches for answers to his questions on the Internet or uses the experience of his acquaintances. But time goes by, and the problem is not solved. This is due to the fact that proper nutrition must be selected individually, based on lifestyle, accumulated deficits in the body, etc. As a rule, it is better to immediately contact a nutritionist and get professional advice, otherwise you can get even more confused and acquire physical pathology.
